| Which plan to pick | Start on the free Individual tier; it is the whole point. If you hit the weekly limits and you also use Gemini for other things, Google AI Pro at $19.99 is a sensible step. Ultra only makes sense for full-time developers. | If you already have ChatGPT Plus, you have Codex: just try it. If you are choosing between this and Claude Code with no existing subscription, Plus at $20 and Claude Pro at $20 cost the same, so pick whichever chat assistant you prefer. If you outgrow Plus, Pro starts at $100 and has no five-hour limit for now. The $200 tier gives new subscribers less usage than it used to, and Ultrafast mode is only on the $500 tier. | Personal. If you have Claude Pro, run Claude Code inside Zed and you are done. Pro only makes sense if you want Zed's built-in assistant and edit predictions without setting up API keys. |
